Embodiment 1

[0054] The weight of the raw material and the particle size of the condensed nuclei (unit μm) of the plant protection UAV aerial pesticide application adjuvant (abbreviated as the anti-flying adjuvant) for reducing the amount of pesticide usage described in Examples 1 to 7 are as shown in Table 2 below Show.

[0055] Table 2 The raw materials of the anti-flying additives of Examples 1 to 7 and the particle size of the condensation nuclei, in g

[0057]

Embodiment 3

[0126] Example 3 The particle size of the condensed substance is controlled at 2 μm, so that the corresponding droplet size is ≤50 μm. Outdoor plant protection drones apply pesticides by air, and the temperature, humidity, wind direction, and wind force are greatly affected, and the drift of the droplets is large. The interference ability of the crosswind is weak, the evaporation amount is large during the movement of the fog droplets, and the settlement is slow. But embodiment 3 meets biological optimal particle size, has excellent control effect to the adults of flying in grassland locust extermination and closed space (such as steel structure greenhouse), is suitable for plant protection UAV aerial spraying under certain conditions, to Reducing the use of pesticides has an important auxiliary effect.

[0127] Thus it is proved that the scientific ratio of the components in the plant protection UAV aerial pesticide application adjuvant prepared in Examples 1 to 7 to reduce t...

Abstract

An embodiment of the invention relates to an aerial pesticide application assistant and a preparation method and application thereof, belonging to the field of pesticide adjuvants. The aerial pesticide application assistant comprises the following raw materials by mass: 0.5-3.0% of large-molecular-weight hyaluronic acid, 0.05-1.0% of small-molecular-weight hyaluronic acid, 1-5% of a a fluorocarbon surfactant, 1-15% of soybean lecithin, 1-10% of a condensation nucleus substance, 1-10% of water-soluble vitamin E, 1-15% of an emulsifier and 0.05-5% of a suspending aid, with the balance being water, summing to 100%, wherein the particle size of the condensation nucleus substance is 2-10 [mu]m, the molecular weight of the large-molecular-weight hyaluronic acid is 400-8000 KDa, and the molecular weight of the small-molecular-weight hyaluronic acid is 8-30 KDa. By accurately controlling the particle size of the condensation nucleus substance, adjusting the fog drop spectrum of spraying liquid medicine, reducing the drifting of fog drops and improving the deposition rate and the adhesion effect of the fog drops, a pesticide use amount can be effectively reduced by 30-70% after the condensation nucleus substance is added.

Description

technical field [0001] The invention relates to the technical field of pesticide adjuvants, in particular to an aerial pesticide application adjuvant especially suitable for plant protection drones capable of reducing the amount of pesticides used, as well as its preparation method and application. Background technique [0002] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] Four departments including the Ministry of Education, the Ministry of Science and Technology, the Chinese Academy of Sciences, and the National Natural Science Foundation of China jointly launched the "10,000 Scientific Problems" collection activity in 2007, among which the dose delivery of pesticides was among them. [0004] During th...
